A skate board has a platform, at least one supporting frame integrally formed on a bottom surface of the platform and extending parallel to a longitudinal direction of the platform, and a plurality of wheel trucks fixed with the supporting frame. At least one plurality of assembly holes is defined in the supporting frame and a center of each hole follows a curved bottom end face of the supporting frame. Each one of the wheel trucks includes a wheel axle disposed substantially perpendicular to the longitudinal direction of the platform and extending through one of the plurality of assembly holes. At least two wheels are rotatably mounted on each wheel axle, whereby the skate board is intended to support a user operating in a pitching way to advance the skate board on the ground, so as to simulate sea surfing on the dry land.
